1. Lemon and Salt for Sweat Stains

Use for: Armpit and collar stains caused by sweat.

How to do it:

Cut a fresh lemon in half and rub it directly onto the stained area.

Sprinkle a generous pinch of salt over the lemon juice.

Gently rub the fabric together or with a soft brush.

Let it sit in the sun for 30–60 minutes for natural bleaching.

Wash as usual.

Why it works: Lemon is a natural bleaching agent, and salt helps lift and break down protein-based stains.
